Abstract

Der Hinterachs-Lastanteil und damit die Richtungsstabilität gewisser Fahrzeuge, beispielsweise solo fahrender Sattelzugmaschinen, sinkt bei höheren Fahrzeugverzögerungen erheblich.The rear axle load share and thus the Directional stability of certain vehicles, for example solo tractor units, decreases with higher vehicle decelerations considerably.

Zur Verbesserung der Richtungsstabilität dieser Fahrzeuge bei hohen Fahrzeugverzögerungen schlägt die Erfindung vor, bei Fahrzeugen mit durch Druck betätigten Bremsen im Falle einer einen vorbestimmten Grenzwert (FMS) unterschreitenden Fahrzeugmasse (FM) den der Vorderachsbremse (3) zuführbaren Druck auf einen vorbestimmbaren Druckgrenzwert (PVAOG) zu begrenzen.

Figure 00000001
In order to improve the directional stability of these vehicles in the event of high vehicle decelerations, the invention proposes, in the case of vehicles with pressure-actuated brakes in the event of a vehicle mass (FM) falling below a predetermined limit value (FMS), that the pressure which can be supplied to the front axle brake (3) is reduced to a predetermined pressure limit value (PVAOG). to limit.
